"she doesn't deserve the consequences" is different than scapegoating. Scapegoating means she's the sole person being blamed for the failures of a larger group.

From the article:

"pursued penalties and criminal charges only against the nurse and not the hospital itself...Vanderbilt received no punishment for the fatal drug error...appears to support defense arguments that Vaught's fatal error was made possible by systemic failures at Vanderbilt."

That certainly seems to lay claim that there are more issues than the single nurse. Holding others accountable doesn't negate her culpability but it would prevent her from becoming a scapegoat.
